Passing values from Java bean to JSP

Question

I am currently working on some legacy code and want to know if is possible to bind values that are not just string but arrays.

When I look at the code I see there's a binding between jsp and java bean i.e JSP

<input type="hidden" name="userId" value="${dataBean.userId}"/>

BACK END

private String userId;

I'm trying add another value, which is a list but it's not working when I do the following

<input type="hidden" name="availableUsers" value="${dataBean.availableUsers}"/>


private String[] availableUsers;

I suspect this is due to the fact that the field it's an array,how can I pass it to the front end?
